The pictures are still not showing up when using my usual browser but I've had a look at them using a different browser (MS Edge).
I agree that the item issuing from the half-wheel (?) looks like an Apfelkreuz on the tankard and like a sword on the flatware. Maybe they are meant to be the same but different engravers interpreted them differently, or they belonged to different branches of the same family.
I was wondering if the arms belong to a family in the German/Swiss/Netherlands area. The name Muchall-Viebrook suggests perhaps the latter and the Fleur-de-Lys might possibly indicate the area of modern Belgium then part of France.
All this is speculation, I am not well-acquainted with European heraldry. However I did find the following on-line reference (website : mistholme.com) which I quote in part:
"Particularly in German heraldry, we find examples of partial wheels: a quarter-wheel, as in the arms of von Billick, or a half-wheel, as in the arms of Rusetzker [Siebmacher 73]. The orientation of the partial wheel (e.g., “dexter half of a wheel”, as in the illustration) must be specified in blazon."
As this was the only reference to half-wheels that I could find either on-line or in my own reference books, I am inclined towards a north European origin rather than British to these Arms.
